IT in construction: aligning IT and business strategies

The extent to which information technology (IT) infrastructures and strategies are aligned with business processes and strategies varies widely along firms. The objective of this paper is to explain the success or failure of IT in construction firms by focusing on the alignment (or lack of it) between business strategy, IT strategy, organizational infrastructure, and IT infrastructure. It is hypothesized that the ‘fit’ among these elements, the domains of the Strategic Alignment Model, is positively related to the Business Value of IT in Construction. The IT Business Value is evaluated in terms of efficiency, effectiveness and business performance. By applying the Strategic Alignment Model to the Dutch construction industry, it is shown that the inadequate alignment between these domains is a major reason for the modest added business value from IT investments in this industry. The first lack of alignment is the technology shortfall: hence IT contributes in an inadequate way to strategic processes of construction firms. The second lack of alignment is the strategy-shortfall: hence the firm strategy impedes the implementation of IT that could generate a high business value

Study of the leptonic decays of pseudoscalar B,DB, D and vector B∗,D∗B^*, D^* mesons and of the semileptonic B→DB\to D and B→D∗B\to D^* decays

We present results for different observables in weak decays of pseudoscalar and vector mesons with a heavy $c$ or $b$ quark. The calculations are done in a nonrelativistic constituent quark model improved at some instances by heavy quark effective theory constraints. We determine pseudoscalar and vector meson decay constants that within a few per cent satisfy $f_V M_V/f_P M_P=1$, a result expected in heavy quark symmetry when the heavy quark masses tend to infinity. We also analyze the semileptonic $B\to D$ and $B\to D^*$ decays for which we evaluate the different form factors. Here we impose heavy quark effective theory constraints among form factors that are not satisfied by a direct quark model calculation. The value of the form factors at zero recoil allows us to determine, by comparison with experimental data, the value of the $|V_{cb}|$ Cabbibo-Kobayashi-Maskawa matrix element. From the $B\to D$ semileptonic decay we get $|V_{cb}|=0.040\pm0.006$ in perfect agreement with our previous determination based on the study of the semileptonic $\Lambda_b\to \Lambda_c$ decay and also in excellent agreement with a recent experimental determination by the DELPHI Collaboration. We further make use of the partial conservation of axial current hypothesis to determine the strong coupling constants $g_{B^*B\pi}(0)=60.5\pm 1.1$ and $g_{D^*D\pi}(0)=22.1\pm0.4$. The ratio $R=(g_{B^*B\pi}(0) f_{B^*}\sqrt{M_D})/ (g_{D^*D\pi}(0) f_{D^*}\sqrt{M_B})=1.105\pm0.005$ agrees with the heavy quark symmetry prediction of 1.Comment: 19 Latex pages,6 figures, references added, corrected typos, content enlarge

Studi Desain Struktur Bidang Lipat yang Memikul Beban dengan Efektif dan Efisien A Design Study On Folded Plate Structure Which Carries Load In Such An Effective And Efficient Way

Analisis struktur bidang lipat menggunakan program komputer SAP 2000 telah dilaksanakan dalam penelitian struktur bidang lipat, setelah penelitian sebelumnya meneguhkan bahwa bahan struktur bidang lipat yang paling sesuai untuk bangunan gedung adalah beton bertulang. Hasilnya menunjukkan efektifitas struktur dalam memikul beban dibandingkan pelat datar tanpa lipatan. Dalam studi awal komparasi sudut pelat lipat, empat kemiringan dari 15o hingga 60o dengan besaran volume yang sama, telah disimulasikan dengan hasil kemampuan yang berbeda-beda. Pemodelan struktur bidang lipat menggunakan bentuk dan ukuran struktur bidang lipat gedung Pusat Pembinaan Sumberdaya Manusia (PPSM) milik Yayasan Tenaga Kerja Indonesia (YTKI) di Jalan Gatot Subroto 44, Jakarta, yang bentangan atapnya 25 m'. Pemodelan dilakukan dalam dua tahap. Tahap pertama adalah struktur bidang lipat atapnya saja, yaitu struktur bidang lipat memanjang (‘longitudinal'). Pada tahap ke dua, struktur bidang lipatnya dibuat berbentuk portal dua sendi (‘two- hinged folded plate frame'). Analisis tahap ke dua menggunakan software LS Dyna dengan metoda elemen hingga (‘finite ele ment') dengan keadaan struktur bidang lipat sepenuhnya terjepit di ujungnya dan terjepit parsial di kedua tepinya. Pengaturan ini dapat memberi kekuatan maksimum dari penampang bidang lipat. Analisis struktur ini menunjukkan bahwa struktur bidang lipat patut dipertimbangkan sebagai alternatip rancangan struktur atap berbentang lebih dari 15 m'

Penelitian ini mengkaji pemodelan limpasan permukaan secara dinamis di sub daerah aliran sungai (DAS) Kuning, Kabupaten Sleman dan Bantul, Provinsi D. I. Yogyakarta. Model limpasan pemukaan dibuat untuk mensimulasikan limpasan permukaan harian di sub DAS Kuning yang terjadi selama 31 hari di bulan Januari tahun 2009. Berdasarkan perhitungan dengan menggunakan metode bilangan kurva, akumulasi limpasan permukaan harian di outlet sub DAS Kuning cukup bervariasi dari 0 hingga 21.5 mm. Limpasan permukaan terbesar terjadi pada tanggal 28 Januari 2009. Model dinamis limpasan permukaan ini diuji ketelitiannya dengan menggunakan pendekatan nilai debit tertinggi yang dihasilkan model. Nilai ini dibandingkan dengan debit puncak di outlet yang dihitung dengan menggunakan metode Manning. Debit yang dihasilkan model sebesar 93.72 m/detik sedangkan debit puncak di outlet sub DAS Kuning sebesar 123.1 m/detik

Implikasi Pembatalan Undang-undang Nomor 7 Tahun 2004 Tentang Sumber Daya Air terhadap Perusahaan Pengelola Air (Pdam Kota Surakarta dan PT Tirta Investama Klaten)

This law article is written in order to determine the implication of abrogated law number 7 year 2004 on water resource into government\u27s water management company and private\u27s water management company, in this case is PDAM Kota Surakarta and PT Tirta Investama Klaten. The writer using empirical research which tries to identify law that live in society based on fact that happen in the location, and the writer got the answer by interviewing the head of legal unit PDAM Kota Surakarta and HRD manager PT Tirta Investama Klaten. Implication of abrogated law number 7 year 2004 on the Government is the legislation as rules of law implementation water management does not apply, so as a legal umbrella reintroduced Irrigation and molded Government Law No. 121 and 122 in 2015 as an implementing regulation of the law on water resources. Both the Government Law is to restore the priority right to control and exploit the water resources to the country\u27s state and public enterprises. Regulation No. 121 Year 2015 on Exploitation of Water Resources regulates the private company that will run the business in the field of water resources must cooperate with State or local government in the region, while private companies are already doing business in the field of water resources before Law of water resources canceled still run the business until the contract expires, and if it will be extended to refer to the latest rules on water resources. Many important things are not regulated by the Water Act, therefore the government should immediately prepare a draft water resource management was good and ideally suited to the concept of domination and exploitation of water resources by the State

REAKSI PASAR TERHADAP INFORMASI ARUS KAS DENGAN VOLUME PERDAGANGAN SEBAGAI VARIABEL MEDIASI

This study aims to examine whether the information of cash flows reflected in Cash flow ratio used by investors to make investment decision, reflected in trade volume activity and the companies’ stock return. Multiple regression analysis is used to examine the data on the companies listed into LQ 45 index for period 2017 - 2019. The result reveals that cash flow return on asset disclosure markedly affected the trading volume activity and trading volume activity disclosure markedly affected the stock return. This implies that investors took into cash flow return on asset ratio in their decision making. On the other side, the study cannot prove the association of other independent variables affected to the investor into investment decision making. Penelitian ini bertujuan untuk mengetahui apakah informasi arus kas yang tercermin pada rasio arus kas digunakan oleh investor untuk mengambil keputusan investasi yang tercermin pada volume perdagangan saham dan return saham. Analisis data menggunakan analisis regresi berganda. Penelitian ini dilakukan terhadap perusahaan yang selalu masuk dalam indeks LQ 45 periode 2017 -2019. Hasil penelitian menyimpulkan bahwa cash flow return on asset berpengaruh signifikan terhadap volume perdagangan saham dan volume perdagangan saham berpengaruh signifikan terhadap return saham. Hal ini menandakan bahwa investor mempertimbangkan informasi arus kas pada rasio cash flow return on asset untuk membuat keputusan investasi. Sedangkan variabel bebas lainnya tidak terbukti mempengaruhi investor dalam menentukan kegiatan investasinya
